Vhen reached its proper position the thumb nut is operated so as to grip the side of the socket vbetween the Washer or thumb nut and the the socket is inclined to the line of movement of the handle. In the case of the device illustrated in Figures 4 and 5 the handle is in like manner forced in any desired Way into the socket and of course it may be drawn into the socket at least in part by operating the thumb nut but in any event when in its extreme position it is secured by turning the thumb nut. v y

Thesel devices arev `commonly made of aluminum and metal somewhatdiihcult to machine but the handle at least at the mouth of the socket should be in Secure contact therewith'to avoidA rocking or movement of the 'handle in the socket of the bail.

This results in the handle being securely held Withinv the socket and reduces to a minimum the tendency of the handle to Work in the socket in any manner and thus reduces to a minimum the strain onthe securing parts and their tendency to vget out of operative condition` A handle comprising.,r a partadapted to be 'secured and provided iivith a tubular socket, a handle shaft having 'an end adapted to be received in the socket, a pin attached to the handle shaft and projecting y through a longitudinal slot in the socket and a thumb nut on the outside of the pin overlying the slotww'hereby rotational movement of the handle in the .socket is prevented andv longitudinahinoifement may be permitted or preifented at-thev Will of the user.
